Experience with Promise Tech. arrays/jbod''s?
Greetings, In looking for inexpensive JBOD and/or RAID solutions to use with ZFS, I''ve run across the recent "VTrak" SAS/SATA systems from Promise Technologies, specifically their E-class and J-class series: E310f FC-connected RAID: http://www.promise.com/product/product_detail_eng.asp?product_id=175 E310s SAS-connected RAID:

X45xx storage vs 7xxx Unified storage
We are looking at adding to our storage. We would like ~20TB-30 TB. we have ~ 200 nodes (1100 cores) to feed data to using nfs, and we are looking for high reliability, good performance (up to at least 350 MBytes /second over 10 GigE connection) and large capacity. For the X45xx (aka thumper) capacity and performanance seem to be there (we have 3 now) However, for system upgrades , maintenance

3510 JBOD ZFS vs 3510 HW RAID
Hi there Is it fair to compare the 2 solutions using Solaris 10 U2 and a commercial database (SAP SD scenario). The cache on the HW raid helps, and the CPU load is less... but the solution costs more and you _might_ not need the performance of the HW RAID. Has anybody with access to these units done a benchmark comparing the performance (and with the pricelist in hand) came to a conclusion.

improve meta data performance
We have a SunFire X4500 running Solaris 10U5 which does about 5-8k nfs ops of which about 90% are meta data. In hind sight it would have been significantly better to use a mirrored configuration but we opted for 4 x (9+2) raidz2 at the time. We can not take the downtime necessary to change the zpool configuration. We need to improve the meta data performance with little to no money. Does anyone

Performance with Sun StorageTek 2540
Under Solaris 10 on a 4 core Sun Ultra 40 with 20GB RAM, I am setting up a Sun StorageTek 2540 with 12 300GB 15K RPM SAS drives and connected via load-shared 4Gbit FC links. This week I have tried many different configurations, using firmware managed RAID, ZFS managed RAID, and with the controller cache enabled or disabled. My objective is to obtain the best single-file write performance.
